To @ZZ whom t may concern:

Beit known that we, EDWARD C. BOYER and FRANK RADFORD, citizens of the United States, residing at Dayton, in the county1 of Montgomeryand State of Ohio, have invented certain new and useful Improvements in Oar- Pushers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in car-pushers, and more particularly to that form of such devices in which are employed means for forcing forward a car-wheel and an automatically-operated chock for following the said Wheel and preventing return thereof.

It consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter described and fully claimed.

In the accompanying drawings, Figure l represents a perspective view of a car-pusher embodying the features of our invention; and Fig. 2 represents an inverted perspective view of the same,the operating-lever being omitted. Fig. 3 represents a longitudinal section on line 3 3 of Fig. 1, the relative position of a car-wheel and rail being shown in dottedlines.

In the art to which this invention relates a fulcrumed lever has been employed for forcing forward a car by Contact with its wheel and a spring-pressed chock has been used for following a car-wheel for preventing the return thereof; but serious objections have arisen to the present form of such devices, among which might be mentioned the fact that no means have been employed for positively guiding the chock and following the wheel, whereby said chock has been subject to lateral displacement, producing liability of breakage. The base carrying the fulcrum and its lever in the previously-employed forms of earpushers have usually been without other means than its frictional contact with the rail for preventing sliding thereof, and in order to overcome these and other disadvantages and provide a cheap, simple, and efficient device we employ, as seen in the drawings, a base, as 1, formed of suitable material and provided with upwardly-extending edge flanges, as 2 2, extending longitudinally and bent inwardly at a right angle for forming grooves for receiving and guiding a flat plate, as 3, carrying a chock 4, which plate is designed to move longitudinally within said groove and be held thereby against lateral movement.

Preferably formed integral with and extending upwardly from approximately the center of base 1 is a suitable lug, as 5, designed to have pivotally secured thereto an operatinglever G, the said lug forming the fulcrum for said lever. The lever 6 is preferably apertured, as at 7, which aperture is designed to inclose lng 5, and a pin, as S, is passed through the lever 6 and lug 5 for pivotally securing the lever in place. The lever G is preferably formed with a curved end, as 0, designed to contact with the periphery of a carwheel when in operation. The lever 6 may be of any desiredlength and is preferably bent at an obtuse angle for bringing the outer end thereof within easy reach of the operator. The chock It may of course be formed of any preferred shape; but we usually employ a chock provided with an upper concaved face designed to snugly fit the contour of the periphery of a car-wheel, and the underface thereof is usually made dat to rest upon the rail. The chock et is preferably formed with downwardly-extending lugs, as 10 10, one upon either edge thereof, the space between said lugs being equivalent to the Width of a rail, so that in operation the under face of the chock will rest upon the rail and the lugs 10 10 will remain in contact with the edges of said rail for guiding said chock in its movement. A suitable bolt, as 11, is carried by the rear end of plate3 and passes through lug 5 at the base thereof. The bolt 11 is preferably surrounded by a spring, as 12, which spring has one end pressing the rear end of plate 3 and the opposite end pressing the rear wall of lug 5. It will be seen that the lug 5 is positioned in the path of movement of plate 3, whereby when the chock 4 isv moved rearwardly against the pressure of spring 12 the rear end of said plate is designed to contact with said lug and have its movement limited thereby, it of course being apparent that as soon as plate 3 is freed it will move forward under pressure of spring 12.

The base 1 is formed at either edge upon its under face with a broken longitudinal ICO flange, as 13, the space between such flanges being the same asthat between lugs 10, whereby the base 1 may rest upon the rail and have its flanges extend upon either side thereof for preventinglateral displacement. Each flange 13 preferably carries a pair of spaced laterally-extending lugs, as 1414, each of said lugs being provided with a suitable threaded aperture.

Extending transversely of the base l and having its ends fit snugly between the pairs of lugs 14 is a suitable knife 15. vThe ends of knife 15 are apertured to register with the apertures of lug 14 forreceivingsuitable bolts or other securing means, as 16. The under edge of knife 15 is cut away, as at 17 17, so that said knife will conform tothe transverse contour of a rail and snugly fit the same, the longitudinal rear'corner of said knife forming the biting or engaging edges thereof, whereby in operation said base l willbe positively held against sliding.

`In operating the present form of car-pusher the base 1 is placed upon a rail with the flanges 13 engaging either side thereof, the lugs 10 also engaging their respective sides of the rail, the chock 4. being in contact with the periphery of a car-wheel, the said base 1 having been placed as near the chock 4 as the rear end of plate 3 and lug 5 will permit. The round or curved end 9 of lever 6 will then be in contact with the periphery of the car-wheel and downward movement of the outer end of said lever will cause a forward movement of the wheel, the curve of the contacting end of lever fi causing a forward throw of the wheel as distinguished from the upward lifting action caused by thecommon form of fulcrumed lever provided with a fiat contacting end. Of course as the car-wheel moves forwardly the spring 12 will cause the chock 4 to closely follow the same and prevent any return movement thereof.

It will be seen by reference to Fig. 2 that the blade 15 in addition to being cutaway to fit the contour of the upper edge of the rail is beveled rearwardly throughout the cutaway portion of the edge, whereby the rear longitudinal corner, as above suggested, will form the biting edge of the knife.

Having thus fully described onrinvention, what we claim as new, and desire to secure byfLet-ters Patent, is-

1. In a car-pusher, the combination of a base adapted to rest upon a rail and provided with flanges on either side for engaging the sides of the rail, upwardly and inwardly extending flanges arranged along a portion of the upper edges of the base opposite each other and forming guideways, an inclined slidable chock provided with a relatively long, rearwardly-extending plate of substantially the same width as the chock and base, said plate fitting and moving in said guideways,

a spring interposed between the rear end of the plate and said base for causing the chock to follow the wheel,v and a lever mounted on the base for moving forward the wheel of a car, substantially as described.

2. In a car-pusher, the combination of a base provided centrally with an upwardly-extending inclined lug, an operating-lever having its head portion apertured to the rear of its nose, the lug on the base extending through said apertured portion of the lever and connected to such lever by a pivot, an inclined toe having a relatively long rearwardly-extending flat plate adapted to be slidably mounted on said base, inwardly-turned flanges on the top of said base, a rearwardly-extending bolt carried by said plate, a spring coiled about said bolt and interposed between the rear end of the plate and the lug, the rearward movement of the plate being thus limited.

3. A car-pusher comprising in its construction a base, recessed or notched flanges extending downwardly from the longitudinal edges thereof, a pair of lugs extending laterally from each of said flanges and spaced apart, and a knife extending transversely of said base, having its edge cut away to snugly fit the contour of the upper edge of a rail, and each end of said knife being secured between one of the pairs of said laterally-extending lugs, substantially as described.

4. Acar-pusher, comprisinginits construction a base, an operating-lever carried thereby, and a transversely-arranged knife secured in the under face of said base and designed to engage a rail for preventing sliding of the base, the under edge of said knife being ont away to t the contour of the upper edge of the rail, and also being beveled rearwardly for forming a biting edge of its rear longitudinal corner, substantially as described.

5. A car-pusher, comprisinga base adapted to fit -upon a car-rail, a fulcrumed lug extending upwardly from said base, aleverprovided with an opening at a point to the rear of its nose for fitting upon said lng and pivoted upon and holding the same in position, the lever being thus pivoted comparatively far from the wheel which it is to engage, a nose formed on the lever which is rounded at its point on its upper side so that when the handle end of the lever is depressed, the said nose will so slip upon the surface of the wheel that it will tend to push the wheel forward on the track, instead of lifting it therefrom, substantially as described.

In testimony whereof we hereunto affix our signatures in presence of two witnesses.
